Consumer durables and risky borrowing: The effects of bankruptcy protection

There exist substantial differences in the generosity of bankruptcy protection across U.S. states. This paper exploits cross-state variation in exemption levels to assess the dual role of durable goods as informal collateral for unsecured debt and self-insurance against bad shocks to earnings. The generosity of bankruptcy protection is found to change both the incentives and the ability of households to accumulate durable wealth. The gains from a high level of insurance are reduced by the effect of tighter credit constraints, so that the net effects of a change in exemption are very small. A more generous bankruptcy regulation reduces net durable wealth in the first half of the life cycle. In addition, the optimal level of exemption is positive but low.     

Optimal execution with uncertain order fills in Almgren–Chriss framework

The classical price impact model of Almgren and Chriss is extended to incorporate the uncertainty of order fills. The extended model can be recast as alternatives to uncertain impact models and stochastic liquidity models. Optimal strategies are determined by maximizing the expected final profit and loss (P&L) and various P&L-risk tradeoffs including utility maximization. Closed form expressions for optimal strategies are obtained in linear cases. The results suggest a type of adaptive volume weighted average price, adaptive percentage of volume and adaptive Almgren–Chriss strategies. VWAP and classical Almgren–Chriss strategies are recovered as limiting cases with a different characteristic time scale of liquidation for the latter.

Exponential utility maximization under partial information

We consider the exponential utility maximization problem under partial information. The underlying asset price process follows a continuous semimartingale and strategies have to be constructed when only part of the information in the market is available. We show that this problem is equivalent to a new exponential optimization problem which is formulated in terms of observable processes. We prove that the value process of the reduced problem is the unique solution of a backward stochastic differential equation (BSDE) which characterizes the optimal strategy. We examine two particular cases of diffusion market models for which an explicit solution has been provided. Finally, we study the issue of sufficiency of partial information.     

Regularity and Pareto improving on financial equilibria with price-dependent borrowing restrictions

We consider a pure exchange, general equilibrium model, with two periods and a finite number of states, commodities, numeraire assets, and households. Participation in the asset markets is restricted in a household specific manner, imposing upper bounds on the amounts of borrowing which can be obtained using assets. Those bounds are assumed to depend on asset and commodity prices. After establishing existence of equilibria, we show that, generically in the set of the economies, equilibria are finite and regular. Then, we restrict our attention to the significant set of economies in which some associated equilibria exhibit a sufficiently high number of strictly binding participation constraints. We prove that, generically in that set, those equilibria are Pareto improvable through a local change of the participation constraints.     

Differentiated goods in a dynamic Cournot duopoly with emission charges on output

We extend the dynamic Cournot duopoly framework with emission charges on output by Mamada and Perrings (Econ Anal Policy 66:370–380, 2020), which encompassed homogeneous products in its original formulation, to the more general case of differentiated goods, in order to highlight the richness in its static and dynamic outcomes. Each firm is taxed proportionally to its own emission only and charge functions are quadratic. Moreover, due to an adjustment capacity constraint, firms partially modify their output level toward the best response. Like in Mamada and Perrings (Econ Anal Policy 66:370–380, 2020), the only steady state coincides with the Nash equilibrium, and it will be considered admissible when it guarantees the positivity of the marginal emission charge. We find that the full efficacy of the environmental policy, which applies to an equilibrium that is globally asymptotically stable anytime it is admissible, is achieved in the case of independent goods, as well as with a low good interdependence degree in absolute value, independently of being substitutes or complements. When goods are substitutes and their interdependence degree is high, the considered environmental policy is still able to reduce pollution at the equilibrium, but the latter is stable just when the policy intensity degree is large enough. When instead goods are complements and their interdependence degree is high in absolute value, the considered environmental policy produces detrimental effects on the pollution level and the unique equilibrium is always unstable, when admissible. This highlights that, from the static viewpoint, even in the absence of free riding possibilities, the choice of the mechanism to implement has to be carefully pondered, according to the features of the considered economy.

     

Nontradable goods prices and per-caita income: an application to regional Korean data

A system of demand equations (given oligopolistic interdependence amon firms) is derived and estimated for two four-digit SIC code industries to explain firms' R&D behaviour through time. The two industries chosen are the perfume, cosmetic and toiletries (PCT) industry, and the drug industry. The industries chosen belong to the same two-digit SIC code classification called the Cchemical and Allied Products industry but not in the drug industry. The introduction of the R&D tax credit in 1981, however, reduced the tendency to free-ride in both industries.     

Can governance help in making an IPO “successful”? New evidence from Europe

This paper investigates the determinants of a “successful” IPO from a corporate governance perspective upon a representative sample of European listings from 2000 to 2015. We use an extensive dataset of market performance, financial data, and corporate governance characteristics to run the investigation. Differently from previous studies, our analysis embraces both a short‐term perspective and a medium–long‐term perspective, where the board of directors seems to perform different tasks, moving from a value creation to a value protection strategy. Among the others, we find that board size, board independence, and their qualifications, together with their experience in other boards, are associated with a positive performance of the IPO in a short‐term horizon and in the medium–long‐term period, although significant differences emerge among those time perspectives.     

Talent Management Practices in IT Companies from Emerging Markets: A Comparative Analysis of Russia,India, and China

ABSTRACT

In this article, the authors review talent management practices in information technology (IT) companies from Russia, India, and China, discussing their differences and similarities. Using the emerging market context, the authors debate the factors influencing talent management, specifically in IT companies. The article examines the relevant research on the main talent management issues in Russia, India, and China, and offers one of the first intercountry comparative analyses of talent management practices in IT companies from emerging markets. The authors argue that although talent management practices are influenced by different institutional and cultural factors, there are similarities and differences that can be explained by the emerging market and industry-specific contexts.
